I am taking this C+ +programming class online and is really struggling learning the concept. Would someone be so kind to help me out with this problem:

A weather station will take 3 temperature readings each day for 7 days (Celsius) before reporting the aggregate data.
I would like to create a program that will read in the 21 Celsius temperature values and store the values in a two-dimensional array.
I would also like to create separate functions for the following tasks:
a. Calculate the average temperature
b. Calculate the high temperature
c. Calculate the low temperature
From the main function, I would like to call the functions created to retrieve the average, high, and low temperatures and display the results in both Fahrenheit and Celsius.
I would like to use the following formula to convert from Celsius to Fahrenheit:
Fahrenheit = Celsius * (212 – 32) / 100 + 32

This is what I came up with:

This won't compile. Is there someone that might have some
time to help me out, I really appreciate it.
